Melania Trump's social media warning to children

Melania Trump has spoken about the "destructive and harmful" impact of using social media incorrectly.

Mrs Trump, 48, gave the speech as part of her "Be Best" campaign targeting children during a cyber-bullying prevention conference.

She urged young Americans to "conduct themselves safely and in a positive manner in an online setting" adding that they need to ensure "safe and responsible use of social media”.

"Let's face it," the First Lady said. "Most children are more aware of the benefits and pitfalls of social media than some adults."

But some people just won't listen.

Enter Donald Trump, 72, who just an hour after his wife's speech embarked on another Twitter rant - this time aimed at intelligence analyst John Brennan whom he called "the worst CIA Director in our country's history”.

"I hope John Brennan, the worst CIA Director in our country's history, brings a lawsuit," the tweet read in full.

"It will then be very easy to get all of his records, texts, emails and documents to show not only the poor job he did, but how he was involved with the Mueller Rigged Witch Hunt. He won't sue!"

Minutes later he tweeted: "Bruce Ohr is at the centre of FALSE ALLEGATIONS which led to a multi-million dollar investigation into what apparently didn't happen," the president tweeted. "Darrell Issa, House Oversight. We can take out the word 'apparently.'"

He continued: "Will Bruce Ohr, whose family received big money for helping to create the phony, dirty and discredited Dossier, ever be fired from the Jeff Sessions 'Justice' Department? A total joke!"

Earlier this month the President hit out at the New York Times, tweeting, "The Failing New York Times wrote a story that made it seem like the White House Councel [sic] had TURNED on the President, when in fact it is just the opposite - & the two Fake reporters knew this. This is why the Fake News Media has become the Enemy of the People. So bad for America!"

A day before he tweeted, "All of the fools that are so focused on looking only at Russia should start also looking in another direction, China. But in the end, if we are smart, tough and well prepared, we will get along with everyone!"

No wonder Mrs Trump regularly faces criticism for her "Be Best" campaign when her anti-cyberbullying mission is compared to her husband's social media behaviour.

A spokesperson for the First Lady said that while Mrs Trump is aware of the criticism, it "will not deter her from doing what she feels is right”.

"The President is proud of her commitment to children and encourages her in all that she does," spokeswoman Stephanie Grisham added.
